Application filed March 26, 1924. Serial No. 701,978.

To all whom if may concern:

Be it lrznown that l, EDMUND S. SPINNnr, of Abington, in the county ofPlymouth and State of h/ilassachusetts, ya citizen of the United States,have invented a new and` useful lmprovcment in Machines for Settinglf'iyelcts, Rivets, and the like. of which the following is a full,clear7 and exact description, reference being had to the. accompanyingdrawings, forn'iing a. part of this specification, in explaining itsnature.

The present invention relates to a machine for set-ting eyelets,`rivetsand the like.

The object of the invention is to provide a machine of the abovecharacter which is simple and economic in its structure, etti cient inits operation and Will maintain its` efliciency. and not easily get outof ordcr o-r Wear out.

The invention can best be seen and` understood in the light of thedrawings where anembodiment thereof is shown and in which- Figure 1 is aside elevation of the machine.

Fig. 2 is a plan.

Fig. 3 is a section taken on the line of Fig. 2.

Fig. it is a section taken on the line 't-4|; of Fig. 2.

Fig. 5 is a` section taken on the line 5 5 of Fig. l.

Figs. G and 7, respectively, are side elevations of that part. of themachine carrying the punch and setting mechanism later to be referredto, the figures showing different operative positions assumed by therespective mechanisms in the operation of the machine.

Referring to the draivings:- t

1 represents the frame of the machine. The frame is provided With anunder eX- tending part 2 and overha-nging the same an extending part 3with space 4 between the two parts. Mounted within the space t is alWork table 5, having Within it an opening 6, arranged preferably in anin clined position as shown which is supported by a bracket 7 secured tothe extension 2 of the frame.

lvfouuted upon the frame extensions 2 and 3 are punch and settingmechanisms. The punch mechanism comprises a punch proper the The anvilhas a top surface 14 having thel same inclination as the 'table in orderthat it may assist in the support of the Work on 'the table during thepunching operation, as will later be more fully explained. The anvil 1salso provided With a recedingcentre or core 15 which also assists in thesupport of the Work during the punching operation and by its permittedrecession into the anvil and carrier therefor permits of the punch. 8ente-ring the anvil after passing through the Work when the respectivepunch members are brought into an engaging position with relation to theWork.

The setting mechanism comprises a member 16 having an annular clenchingsurface 17 and extending from this surface a central tubular projection18 which enters the centre of the eyelet during the setting operation.The member 16 is borne by a carrier bar 19 mounted to slide Within aVWay 2O in the part 3 of the frame.

Arranged in opposition to and cooperating with the setting member 16 isa setting member 21 having an annular clenching surface 22 and a springlinger 23 adapted to receive eyelets from an automatic feed during theoperation of the machine, as Will later be explained. During the settingoperation the spring 'linger 23 recedesinto the setting member 21 andcarrier therefor the clenching surfaces 17 and 22 of the respectivesetting members are brought into engagement with the eyelet or Worlr andthe projection 18 of the member 16 enters the centre of the eyelet. ThesettingV member 21 is borne by a carrier 24 slidab-le Within a Way inthe part 2 of the frame.V

The cooperating members and caigriers therefor of both the punch andsetting mechanisms are mounted in opposition to one another above andbelow the table and are slidable upon the frame with a reciprocatingmotion toward and away from one another and the opening in the tableinto and out of engaging positions. The neinbers of the respectivemechanisms preferably all lie in the same plane, which plane is a rightangle to the face of the table. The respective mechanisms are alsoarranged in positions angular to one another and operate along lineshaving relatively such acute angularity that as the mechanisms aresuccessively operated they will engage the work relatively to theopening in the table at a substantially common point, the punchmechanism engaging the work when the setting mechanism is in itsdisengaged, and preferably extreme disengaged, position, and vice versa.

The means for operating and assisting in the support of the punch andsetting mechanisms is also such thatthe two mechanisms will engage thework in such relation to the opening in the table and work laid thereoncovering said opening, that the work will not be elevated above theopening or depressed into the opening during the punching and settingope-rations. In other words, during the punching operation the member 11of the punch or anvil will be elevated to a position where its topsurface 14 will lie substantially within the plane of the top surface ofthe table and will accordingly support the work immediately adjacent thepoint where the hole is made in it as the other cooperating punch member3 or punch proper is passed through the work. In a similar manner duringthe setting operation the member 21 of the setting mechanism will bebrought up intoV a position where its clenching surface 22 will liesubstantially within the plane of the top surface of the table as theclenching surface 17 of the other cooperating member is brought downinto engagement with the eyelet for upsetting it. The under clenchingsurface 22 of the setting mechanism will accordingly assist in thesupport of the eyelet during the setting operation.

It will also be observed that the respective members of the settingmechanism operate along a line or path substantially at a right angle tothe plane of the table in order that the respective clenching surfacesof the setting mechanism may squarely engage the eyelet for effecting a.proper upsetting thereof in relation to the work. VSuch disposition ofthe setting mechanism necessitates that the punch operate at a slightangle with relation to the work with a tendency to make Van inclinedopening through the work, but

such inclination is negligible in practice.

Reference will now be made to the means for operating the punch andsetting mechanisms:

Both mechanisms are operated directly by a pair of levers and 31. Theselevers are mounted on a shaft 32 which has bearing to turn on the framejlust back of the opening 4 between the parts 2 and 3 of the f ame. Thelever 30 is provided with a hub 33 by which it is mounted to turn freelyon the shaft 32. The lever 31 is provided with a hub 34 by which it ismounted on the shaft 32 and is secured thereto'by a setl screw 35 bywhich the lever 31 is secured to the shaft to turn therewith.

The two levers 30 and 31 are siinultane ously actuated by a crank shaft3G through a connecting crank 37. The crank shaft 36 is mounted to turnon the frame of the machine and is turned by a power-driven pulley aswill later be explained. The levers 30 and 31 besides operating themembers of the punch and setting mechanisms assist also in thepositioning of these members.

The general form, arrangement and operation of the levers are asfollows: rl`he lever 30 forward of the shaft 32, on which it is mountedto turn, is bifurcated to provide arms 39 and 40 respectively, the arm39 having a slot 39 therein and the arm 40 a slot 40 therein. Thatportion of the lever extending to the rear of the shaft 32 comprises anarm 41 having within it a slot 41. It is also to be noted that the leveris provided with an offset 42 by which the arm 41 thereof is slightlyoffset from the plane of the arms 39 and 40. to permit of the insertionof one of the crank arms of the crank mechanism later to be referred to.

The lever 31 in the part thereof lying forward of the shaft 32 to whichthe lever is secured is bifurcated to provide arms 43 and 44respectively. The arm 43 has in it a slot 43 and the arm 44 has in it aslot 44. That portion of the lever lying to the rear of the shaft 32comprises an arm 45 having in it a slot 45. The slotted arms to thebifurcated portions of the respective levers extend by the sides of theparts 2 and 3 of the frame in which lie the various movable carriers forthe punch and setting mechanisms. Slots 47 are formed in the frame parts2 and 3 in the sides of these parts facing the projecting arms of therespective levers. These slots extend in directions parallel with thevarious carriers of the punch and setting mechanisms and leadrespectively into the ways in which the carriers reciprocate. Secured toeach one of the carriers is a stud 43 extending laterally therefromthrough the slot 47 adjacent the carrier7 and thence extending to becontained in one of the slotted arms of the two levers 30 and 31. lnthis connection it will be observed that the stud 43 on the carrier 9for the punch member 3 is contained within the slot 43 in the arm 43 ofthe lever 31, and the stud 43 on the carrier 12 for the punch member oranvil 11 is contained within the slot 40 in the arm 40 of the lever 30.On the other hand, the stud 43 on the carrier 19 of the setting member16 is contained within the slot 39 in the arm 39 of the lever 30, whilethe stud 43 on llt) the carrier of the setting` member 2l is containedwithin the slot ll in the arm L14 of the lever-3 Thus arranged-thevarious carriers of therespectivepunch and setting',` mechanisms andmembers carried thereby will be nroperly actuated as the levers and 31are turned in reverse directions.

As previously noted, thelevers 30 and 3l are actuated simultaneously bya crank shait 3G through a connecting crank 37. The crank 37 is adoublevacting crank. lt has a crank arm 5l lixed to the end et the crankshaft 36. This arm bears upon its end a laterally-extending crank pin 52which is contained to lie within the slot in the arm Ll5 et the lever3l. The crank pin .52 has secured tov it a crank arm 53 which liesbetween the arms el and 45 of the respective levers 30 and 3l andextends in a direction reverse to the direction of' the crank arm 5lthrough the axis ot the crank shaft, if such axis were extended, theextension of the crank arm beyond the axis of the crank shalt beingadist-ance substantially equal to the length oi the crank arm 5l. Thecrank arm bears upon its end a laterally-extend ing crank pin .Vi-ilwhich is contained within the slot 43:1 in theiarin 4l ot the lev r 30.

The normal position ot the part-s is substantially that shown in Figs. land` 2. The levers 3() and 3l will beturned to a position where theywill hold the respective members of the punch and setting mechanism indisengaged position. The arms l1 and l5 oit the respective levers 30 and3l together with the. slots l-'t and Lio in 'these are s will occupy ahorizontal position in substantial parallel alignment with one anotherand the respective crank arms 5l and 53 oit' the crank will have asimilar horizontal disposition, their avranggen'ient also beingl suchthat the crank pin a? will be located at the outer end of the slot inthe arm lo of the lever 3l and the crank pin 5l will be located at theinner end oi' the slot ll in the arm AYill ot the lever 3f).

lilith the parts thus disposed and arranged, the turningot' the crankshaft 36 a sii le revolution in a clockwise direction as rved from theside ot the machine shown o5 in l. l will cause the various parts tofunction as follows: As the crank shaft is turned `the crank arm 5l willmove the crank pin :'32 inwardly along the slot 45 in the arm ot thelever 3l and will elevate this arm and, by the roc g oli' the lever,depress its arms i3 and lll, whereupon the punch mem bei' or the punchmechanism actuated by the arin 43 oiE the lever will be moved to anengaging position. weile the member 21 of the setting` mechanism` willbe moved by the arm lll of the lever into a more retracted position.Simultaneously with this operation the crank arm 53 will move the crankpin 54 outwardly along the slot 4l in the arm 4:1 of the lever 30 andwill depress this l (Y b se The extreme engaging position of theV punchmember 8 will be reached when the crank shaft has been turnedsubstantially one quarter oi? a complete turn and the crank. arm 5l isin a position at substantially right angles to the slot e5 in which thecrank pin 52 is working. As the movement of' the crank shaft continuesup to substantially a one halt complete turn the continued movement ofthe crank `arm 5l will move the crank pin 52 further inwardly along theslot 45 in which it is working and there upon the rockingl movement ol'"the lever 3l will be reversed and the punch member 8 of the punchmechanism and the member 2 of the setting mechanism will be moved backto their normal disengaged positions,

The extreme engaging' position ot the punch member or anvil 1l will bereached when the crank shaft has been turned substantially one quarterof a complete turn and the crank arm 53 is in a position at substantially right angles to the slot 411" along which the crank pin 5e isworking. is the movement ofthe crank shaft continues up to substantiallya one half complete turn the continued movement of the crank arm 53 willmove the crank pin 5ft `further outward alongthe sl'ot lll in which itis working` 'and thereupon the rocking movement of the lever 30 will bereversed and the punch member' or anvil ll of the punch mechanism andthe member 16 ot the setting' mechanism will be returned to their normaldisengaged positions.

During' the operation just described the punch member or anvil ll willhave been moved to its full originan'ing` postion with the face lll or"the anvil. suhstantiz'ally flush with the top surface of the table justprior to but practically sin'iultaneously with the time when the punchmember 8 has been moved to a proper engaging position for making a holein the work to receive the eyelet. Vhen the punch member or anvil ll hasreached its lull engaging position and the punch member 8 has:functioned a. aoresaid the member will be moved away from its engagingposition, but the en eagcnnmt ot the member 8 will continue until thecrank arm 5l has been moved to a position et substantially right anglesto the slot 45 in which it is working. By the recession of' the anvil llits surface le will move below the face of the table on which the workis resting and consequently the work will no longer be supported at thepoint or the opening` in the table by the top surface 14 of the anvil atthe very time when the member 8 of the punch is continuing to operate.Consequently the work will be slightly depressed by the punch member 8into said opening. This is undesirable and is obviated by preventing acontinued movement of the lever 31 operating the punch member 8 afterthis member has reached its proper engaging position for making a holein the work. It is accomplished by making a. slight offset GO in the`arm 45 of the lever 31 along the top surface of the slot 45 therein.This offset is so postioned that the crank pin 52 working inwardly alongthe slot 45 will, after the crank arm 51 has moved the punch member 8 toa proper' engaging position, reach the offset and thereupon will cause alag in the operation of the lever 31 and consequently the engagement ofthe punch member 8 with the work will no longer be continued `after thedepression of the anvil 11 has commenced. After the crank pin 52 haspassed the oifset then the rocking movement of the lever 13 will becontinued and both levers will return the members of the punch andsetting mechanisms to their initial disengaged positions.

Thus far the operation attending a substantially one half complete turnof the crank shaft has been explained. The crank pin 52 will then beoccupying its extreme inward position within the slot 45 in which it isworking and the crank pin 54 its eX- treme outward position in the slot41. As the movement of the crank shaft continues the crank pin 52throughthe operation of the crank arm 51 will work outward within theslot 45 in the arm 45 of the lever 31 depressing this arm and, by therocking of the lever, elevating its arms 43 and 44. Thereupon thepunch-member 8, actuated by the arm 43 of the lever, will be moved intoa more disengaged posit-ion, while the member 21 ot the settingmechanism will be moved by the arm 44 of the lever into an engagingposit-ion. Simultaneously with this operation the operation of the crankarm will move the crank pin 54 inwardly along the slot 41 in the arm 41of the lever 30 and will accordingly elevate this arm and, by therocking of the lever, depress its arms 39 and 40. Thereupon the punchmember or anvil 11 will be .moved by the arm 40 of the lever 30 into amore disengaged position and the member 16 of the setting mechanism willbe moved by the arm 39 of the lever 30 into an engaging position.

kThe full engaging position of the setting member 21 will be reachedwhen the crank shaft has been turned substantially a further one quarterturn beyond its half turn and the crank arm 51 is in a position atsubstantially right angles to the slot 45 in which the crank pin 52 isworking. As the movemechanism will be moved back to their normaldisengaged positions.

The extreme engaging position of the setting member 16 will be reachedwhen the crank arm 53 is in a position at substantially right angles tothe slot 41 in the arm 41 of the lever 30 in which the crank pin 54 is iworking. As the movement of the crank shaft continues up to the time ofits complete turn the continued movement of the crank arm 53 will movethe crank pin 54 further inward along the slot 41 in which it is workingand thereupon the rocking movement of the lever 30 will be reversed andthe member 1G of the setting .mechanism and punch member or anvil 11 ofthe punch mechanism will be returned to their' normal disengagedpositions.

During the operation just described the setting member 21 will have beenmoved to its full and proper engaging position with the clenching face22 of this member substantially flush with the top surface of the tablejust prior to but practically simultaneously with the time when the saidmember 16 has been moved to a proper engaging position for upsetting theeyelet. When the setting member 21 has reached its full proper' engagingposition and the setting member 1G has reached an engaging position toproperly cooperate therewith for upsetting the eyelet then the member 21will be moved away from its engaging position, but the member 16 willcontinue to be moved in the direction of a more extreme position ofengagement until the crank arm 53 has been moved to a position atsubstantially right angles to the slot 41 in the arm -1-5 in which it isworking. By the recession of the setting member 21 its clenching surface22 will move below the face of the table on which the work is restingand consequently the work will no longer be supported at the point ofthe opening in the table at the very time when the setting member 16 iscontinuing to operate. ln other words, the setting member 1G will followthe setting member 21 as it recedes and consequently the work will beslightly depressed into the opening in the table. This is undesirableand is obviated by preventingl a continued movement of the lever 30 foroperating the setting member 16 after this member has reached avproperposition to cooperate with the sett-ing member 21 for upsetting theeyelet and before the member 21 has receded. It is accomplished bymaking a slight ott'- set 61 in the arm 41 ot the leverBO along` the topsnriace ot the slet All therein. This oil'set is so positioned that thecrank pin 54- ivorking inwardly along the slot ll will, aiter the crankarm 53 has nioved the settingmember 16 to a proper engaging` position,reach the oilset and thereupon Will cause a lag;i in `the operation cithe lever 30 and consequently the engagementot the setting member 16with the work will no longer be continued after the depression of thesetting` member 2l has cinnmenced. liter the cranlt pin 5ft has passedthe otiset then the roel-ting movement of the lever BO Will be continuedand both levers *ivill return the members ot the punch and settingmechanisms to their initial disengaged positions.

An automatic feed is provided forv the purpose of feeding eyelets ltothe spring finger i3 of the setting` mechanism in order that the fingermay severally pick up the eyelets as they are fed to it and insert theeyelet picked np in the hole punched in the v-:orlr a'i'ter theunetioninggy of the punch mechanism and preliminary to the action ot thesetting' mechanism. To this end an antomatic feeding device ot commontype is employed having` a hopper (3G and a 'feed chute G7 leading` fromthe hopper, and 'from the end ci which chiite the eyelet is picked oliin the usual manner by the springl linge 23 as the chute is reciprocatedor oscillated to present he eyelet to the linger. ln order to obtain a`proper reciprocation or oscilhtion oi the chute, it togetherivith thehopper is mounted upon a slidingl carrier G8 arranged alongside theiframe vand occupying an inclined position in relation thereto Thecarrier has in it a slot @through which errtends a bolt i passed throughthe :traine and retained by a tightening,` not TO. rThe retention or thebolt is sach that its head will draw against the side ot the carrier andrictionally hold it in any position to which it may be mover nfithin therange permitted by the slot Si'. rThe carrier is otherwise slidablysupportedbj,r an upv?ardly-eiztendinp; arm il supported from olii theupper end oi a crank arm 72 on 'the end ot the sha'lit (on which thelevers SO, Si are mounted) by a pin Tel extending laterally from 'thearm il and contained Within an inclined slot T in the upper end oi? thecrank arm T2. Thus arranged the automatic leed will operate as follows:The normal position of the chute is one in which the end ot the chute isaway from the pnnch and setting mechanisms. As the levers and Si areturned ttor moving thenien'ibers ot the punch mechanism into engagingpositions the shaft 32 will turn With the lever 3l and thereby throughthe cranl; arm `72, pin i' and arm 71 move the sliding carrier 65% and'feeding device with it in a 'forward direction until the month ot thechute 6'( and eyelet therein substantially 'within the path 'of thespring` linger 23 ot the setting mecha-n nism. According to theoperation oit the levers 30 and Si previously described their nextlmovement is a reverse movement for moving the members of the punchv andsetting mechanisms bach to their normal or disengaged positions andafterward movingl the members oi the setting mechanism intotheire'ngaging positions. During this first movement or the movement iorreturning" the members of' the punch and setting mech anisms to theiroriginal disengaged po`sitions the reverse movement of the 'shaft 3Qwill not disturb the chute as the pin 74: Will draiv alongl the slot 75in the cr-ank arm 7 This condition remains until the lever 3l haselevated the finger 23 of the setting mechanism to a position Where itwill pick the eyelet oli the end of the chute. The crank arm 72 Willthen have been moved to a position Where it will again be in engagementwith the pin Tet then located at the tor- Ward end ci the slot 75 in theoranti arm and the then continuingl reverse movement oit the shaft 32,attending the operation of the levers 30 and 3l vfor moving the membersot the settingmechanism into an engaging position, will return thechtite to its normal disengaged position. llore it will remain `untilthe members ot the punch mechanism are again moved into an engaging,lposition, 'for' as the levers tnrn to return the members of the settingmechanism to their disengaged position the ensuing reverse turning' ofthe shaft 82 will 'cause the crank arm '72 to draw over the pin 74 byreason of the slot 75 in the end or the arm and consequently will notdisturb the position oi" the chtite. All parts will then be occupyingltheir initial positions preparatory lto the next ensuing` operation ofthe machina In connection with the operation of the automatic leed itwill be further explained that the hopper 66 of the vfeed mechanism isprovided inside the hopper with the usual stirrer or brush (not shown)which turns or oscillates on a pin 'Ti' mounted to turn in bearings onthe .top and bottom Walls ot the hopper. To` this pin an arm 78 istixedlv secured and pivotally connectingl with this arm is a linl; 79loosely mounted on the end of the. bolt laterally extending; 'from theside et the frame. clnding the hopper and chute are reciprocated duringthe operation of the machine the stirrer or brush inside the hopper willbe agitated by the arrangement of the parte thus described.

Thel machine further embodies a clutchorming mechanism having anautomatic release whereby only a single complete turn or rotation .ispermitted the driving shaft -'when the clutch is throivn'iin, thepunchinp of the hole in the Work, application ci? As the feeding` devicein i the eyelet to the work and setting of the eyelet being completedduring such one complete rotation of the driving shaft.

To this end the driving shaft is provided with a pulley 8O mounted toturn loosely upon it and to which pulley powerl is applied in anysuitable manner. The pulley has on its inner side facing the frame anannular ring or flange 8l and projecting laterally from this flange area number of studs 82. Mounted upon the main shaft 32 alongside thepulley on the side thereof provided with the studs is a hub 84. which isfixed to the shaft. This hub has on one side thereof a hub extension Silwith slot 85 in it. In this slot, pivoted to the hub by a pin 86, isarranged a clutch member 87 extending outwardly from the hub extensionin a direction radial to the main shaft and movable into an engaging ordisengaging position with relation to the pulley 80 and studs S2 carriedby it. lVhen in an engaging position the clutch member will be moved toa position where its side S7 will bear against the annular'flange on thepulley, the body of the clutch member then being interposed or lyingwithin the path of the studs carried by the pulley as the pulley isrotated and consequently may be engaged by any one of said studs as thepulley is turned. From this engaging position the clutch member ismovable away from the annular flange on the pulley and out of the pathof the studs thereon. It will also beA observed that the clutch memberhas such extension that the outer end 872 thereof will project beyondthe outer face of the annular flange 8l on the pulley, The clutch memberis yieldingly maintained in an engaging position by means of a spring S8fixed to it and to the hub extension Sel on which the clutch member ismounted.

Mounted on a hub 89 arranged to turn upon a stud 90 fixed to the framein a position beneath the clutch member 87 is an upwardlyextendingclutch-controlling arm 92. This arm turns upon an axis parallel withthevaxis of the main shaft 32 and the upper end of the arm, as the armis pivotally turned, moves in a general direction toward or away fromthe shaft 32 and thereby into different operative positions withrelation to the clutch member 87. The upper end of the arm presents anoutwardly turned portion 93 which when the arm is moved inwardly in thedirection of the main shaft is adapted to bear against the periphery ofthe annular flange 8l on the pulley. This portion of the arm having suchbearing is provided with an inclined side 94. which, when the end of thearm isbearing against the annular flange on the pulley, lies within theplane of the studs on the pulley and just outside the path described bythe studs when the pulley is rotated. The upper end of the ing the frameof the machine and a stop 97.

Attached to the hub 89 on which the clutchcontrolling arm 92 is mountedis a lever 98.

`To the outer end of this lever is secured a spring 99 attached to theframe of the machine, the arrangement being such that the draft of thespring upon the lever will normally hold the arm 92 in its inturnedposition from which position the arm may be released by draft upon alink connected to the opposing inner arm of the lever 9S, the draftbeing applied by any suitable means, preferably by a connected footpedal (not shown).

The operation of the clutch mechanism is as follows: The normal positionof the arm 92 is its inturned position with the upper end 93 of the armbearing against the an* nular flange 8l on the pulley. l/Vhen thuspositioned the clutch member will have bearing against the side 9G ofthe arm resting against the stop 97 and thereby be maintained in adisengaging position with relation to the studs 82 borne by the pulley,and accordingly the pulley when rotated will simply idle upon the shaft32.

Assuming `now that the clutchecontrolling arm is released outwardly bydraft on the link 100, thereupon by the turning of lever 98 the arm 92moved outwardly will release the clutch member 87 into an engagingposition with bearing against the side of the annular flange on thepulley and disposed within the path of the studs S2 as the pulley isrotated. When thus released into an engaging position the face 95 of thearm will bear against the outer end 872 of the clutch member and the armwill thereby be maintained in an outturned position. Immediately uponthe clutch member entering the path of the studs 82 on the pulley itwill be engaged by some one of the studs and the eupon the pulley will,through the clutch member, turn the main shaft 32. As the shaft isturned the clutch n'iember will be turned away from theclutch-controlli]1g arm 92 and thereupon this arm will resume its normalinturned position. rlhe ro tation of the main shaft will continue untilthe clutch member has been brought around to a position where the outerprojecting end 872 thereof will engage the inclined surface 94 of theclutch-controlling arm. lmmediately on contact with this surface theclutch member will ride thereon and be moved inwardly out of the path ofthe stud driving it and onto the side 9G of the arm where it will bemaintained in a disengaged position resting against the stop S7 on thearm and the pulley then left to idle. The release of the clutch memberis commensurate with a single turn or revolution CTX til)
